Like iPhones and iPads, Apple Silicon Macs will use an Apple-designed GPU – which makes complete sense when you consider this is how current iOS devices work, but may be a pause for thought for some high-end users during the transition period.

Tile Based Deferred Rendering

You see, while Intel based Macs contain GPU’s from Intel, Nvidia and AMD, Apple Silicon Macs will use what the company seems fond of calling “Apple family” GPUs.

These use a rendering system called Tile Based Deferred Rendering (TBDR), which iOS devices already use.

It works differently from the Immediate Mode rendering system supported in Intel Macs: While the latter immediately render imaging data to device memory, the former makes more use of the GPU by sorting each element out first before submitting it to device memory.

What advantages does it bring?

The effect is that TBDR rendering delivers lower latency, higher performance, lower power requirements and can achieve higher degrees of bandwidth.
